CHAS. RICE, OF BOSTON, AND S. H. W'HORF, OF ROXBURY, MASSACHUSETTS.

MACHINE FOR PREPARING LEATHER FOR THE'MANUFACTURE OF BOOTS ANDy SHOES.

Specification of Letters Patent' No. 13,827, dated November 20, 1855.

To all whom it may concern:

Be it known that we, CHARLES Rien, of Boston, in the county of Suffolk, and SYL- vANUs H. VHORF, of Roxbury, in the county of Norfolk, State of Massachusetts, have invented a new and useful Machine for Preparing Leather for the Manufacture of Slices; and we do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, figures, and references thereof.

Of such drawings, Figure l, denotes a top view of such machine. Fig. 2, is a side elevation of it. Fig. 3, is a vertical, central and longitudinal section of it.

This machine is intended to be used in preparing leather for the manufacture of shoes or other articles, by cementing the leather or parts thereof together by caoutchouc or other proper cement.

In the said drawings A, B, are two feed rollers having a splitting knife C, placed in front of them. In advance of such devices, is a set of draft rollers D, E, a roller, F, and a rasper or rasping cylinder G, they being arranged with respect to each other and the knife C, as seen in Fig. 3. In the place of 'the rasper or in connection with it there may be employed a perforating or punching roller H and a pressure roller I, disposed over it as particularly seen in said Fig. 3. A cementing brush, K, revolving in atrough L, may be disposed in front of the rasping or perforating machinery and have a guide or pressure roller X, disposed over it.

The external surface of the rasper may be made roii'gh or provided with points to scratch or roughen the surface of the sheet of leather when brought into contact with the same. Soin regard to the punching or perforating roller, its external surface should be provided with a series of punches or awls, a, a, which when the roller is pressed in contact with the leather, may either wholly or partially perforate it.

For operating the mechanism above described which is supported by a suitable framework, as seen at M, there may be a driving shaft N, arranged at the rear end of the frame and carrying a driving pinion gear O, at or near each of its ends. -One of these pinions drives a train of gears I), Q, R, S, T, and U, while the other engages with and operates another such train seen at b, c, d, c, f, in Figs. 1 and 3. The gear,

P, is fixed on the shaft of the lower feed roller of the splitting apparatus, while the gear, c, is fixed on the upper feed roller and is set in motion by the gear c. The gears, Q, and d, are attached respectively to the shafts of the lower and upper draft rollers D, E, and while the gear R, is on the shaft, g, of the rasper, the two gears, S and e, serve to transmit motion to the gears T and f, which respectively are placed on the shafts of the pressure roller, I, and the perforating roller H. On the shaft of the rotary brush, the gear U, is affixed; such gear being for the purpose of imparting motion to the shaft and through it to the brush.

. In using the said machine, a hide or skin is first introduced between the feed rollers of the splitting mechanism and by them is forced against the knife and either split or shaved, the upper portion of the sheet passing over a shelf, V, from whence it is led and introduced between the draft rollers which draw it forward. From the draft rollers it is made to pass between the roller F and the rasper G, and has its under surface rasped or roughened by the latter during its revolution. From the rasper the leather runs over a guide bar, IV, and between the rollers I, and, H, it being punctured or perforated while ruiming between the said rollers I and H. After emerging from them, it should be made to pass between the rotary brush and the roller over it,.and as the former revolves in the cement trough in order to apply a coating of cement to the roughened, rasped or perforated surface of the leather.

It must be evident to any one, that by the immediate application of the cement to the rasped or roughened surface of the leather or before the action of air changes of temand machinery, our invention will be found to possess decided advantages.
